摘要 :为比较西花蓟马Frankliniella occidentalis对不同寄主植物的选择性,本研究采用罩笼法观察了西花蓟马对8种不同蔬菜寄主植物(茄子、甘蓝、辣椒、黄瓜、莴笋、番茄、芹菜、香菜)的选择性,并使用“Y”形嗅觉仪评价了西花蓟马对不同蔬菜的嗅觉行为反应。结果表明,在8种不同蔬菜寄主植物中,西花蓟马对茄子、甘蓝的选择性最高;对芹菜和香菜的选择性较弱,表明西花蓟马对芹菜和香菜表现出忌避性。本研究结果为了解西花蓟马对不同寄主植物的选择提供理论依据。

Abstract
To compare the selectivity of Frankliniella occidentalis for different vegetable host plants, the selection of F.occidentalis for eight different vegetable host plants, including Solanum melongena, Brassica oleracea, Capsicum annuum, Cucumis sativus, Lactuca sativa, Lycopersicon esculentum, Apium graveolens, Coriandrum sativum, were observed by using the cage method, and the Y-tube olfactory apparatus was used to evaluate the olfactory behavioral responses of F.occidentalis to different vegetables. The results showed that, among the eight different vegetable host plants, F.occidentalis had the highest selectivity for S.melongena and B.oleracea. The quantities of F.occidentalis on A.graveolens and C.sativum were the least, which showed the aversion of Foccidentalis to these two plants. The results provided a theoretical basis for strengthening the agricultural control of Frankliniella occidentalis.

西花蓟马Frankliniella occidentalis属缨翅目Thysanoptera蓟马科Thripidae,是一种世界危险性入侵害虫[1]。该虫起源于20世纪70年代美国西部的落基山脉,随后蔓延至美洲、欧洲、非洲、亚洲、大洋洲的69个国家和地区,成为一种世界性的农作物害虫[2]。西花蓟马在我国于2003年6月首次在北京郊区的温室辣椒上发现,目前分布于云南、河北、浙江、山东、新疆等地[34]。西花蓟马寄主作物范围广泛,尤其喜食蔬菜和花卉,如黄瓜、茄子、辣椒、甘蓝、番茄、豆类、非洲紫罗兰、玫瑰、凤仙花、菊花等[57]。西花蓟马利用其锉吸式口器吸食寄主植物叶、芽、花、果汁液,受害植物嫩叶呈白斑点状,皱缩卷曲,甚至黄化、干枯、凋萎,导致无法继续生长,造成大幅减产甚至绝收[89]。此外,该害虫还能传播植物病毒,造成严重的经济损失[10]。
新疆自乌鲁木齐地区发现西花蓟马以来[11],该虫对新疆各地设施蔬菜的为害日益严重,且为害面积也在不断扩大,对设施蔬菜品质造成显著影响。……
